A great scientist claims that the solar energy will lead entirely in future. That will be a great need of this planet in the next coming 20 years. Now we could imagine our self the importance of this valuable energy, because we are now in disaster and facing energy crises. The reservoirs of gas, coal and petroleum is going to be empty. At last we have to search the substitute of it. There is 10,000 times more sunlight than we need to meet 100 percent of our energy needs and the technology needed for collecting and storing it is about to emerge as the field of solar energy is going to advance.
Solar to compete in the next five years
At this time we have not any big planning for accumulating the solar and wind energy. But after seeing the statics of the future, we are serious and doing a valuable research and planning to store these energies. At present supply about 1 percent of the world’s energy needs, but advances in technology are about to expand with the introduction of nano-engineered materials for solar panel making them more efficient, lighter and easier to install and take the demanding benefits.
The researchers said that we are not that far away from a tipping point where energy from solar will be economically competitive with fossil fuels and it could happen in the next 5 years.
In this connection other technologies which will be helpful are solar concentrators, made of huge mirrors that absorb very large amount of sunlight onto a small steam turbine. The energy can be stored by using nano-engineered fuel cells which will be available in the market soon.
You could create hydrogen or hydrogen-based fuels from the energy produced by solar panels and then use that to create for fuel cells.
Other troublesome challenges
Experts think that facing the energy challenge and the other troublesome challenges of the 21st century is simply important to our survival on this planet. Other challenges are:
1- To clean water.
2- Producing better medicines.
3- Securing cyberspace.
4- Improvement in practical reality.
The big and useful inventions gave us the green revolution that increased the production of food as world population grew. The distribution of safe water and electricity, improved health generated an upgraded standard of living for everyone.
However, now the world faces some dark results of these advancements which are the threat of a security disaster, if nuclear and biological weapons fall into the wrong and fanatic hands.
More solutions to upcoming challenges
Other tech solutions for the new century’s big challenges include:
1- Proper monitoring of nuclear weapons components to prevent them from getting in the hands of fanatic.
2- Make an advance in rapid responses to possible bio-weapons attacks.
3- Advances in genetic engineering to address the problem of drug-resistant viruses and bacteria, and to create personalized medicine.
4- Purification of water to meet the demand of shortage of drinking healthy water.
The policy which will be run in the 21st century challenges plan, reveal a more enlightened understanding of role of science and technology in general. This idea is being developed in the context of a globalized world, even though the proposals have been developed in world.
The Copycat is a portable scanner that allows you to simply capture documents even as on the move. The device has an SD card slot built in that consent to 2GB of images to be stored though the memory card isn’t offered with the portable scanner. This ingenious battery operated device allows you to capture books, magazine pages, photos, text and virtually any document you can think in seconds, wherever you may rove. Simply sweep it across the pages and presto, the images are written onto micro SD card equal to 32GB, ready for idiot proof USB drag-and-drop shift to computer or Mac. Capable of storing above 30,000 pages, the Copycat scans color images at an impressive 600 dpi, and comes with effective OCR software that modify text images into editable text in Word, Clipboard or Excel.
